Abstract Most of the planet's diversity is concentrated in tropics, which includes many regions undergoing rapid climate change. Yet, while climate‐induced biodiversity changes are widely documented elsewhere, few studies have addressed this issue for lowland tropical ecosystems. Here we investigate whether floristic and functional composition intact Amazonian forests been changing by evaluating records from 106 long‐term inventory plots spanning 30 years. We analyse three traits that...
Thermal sensitivity of tropical trees A key uncertainty in climate change models is the thermal forests and how this value might influence carbon fluxes. Sullivan et al. measured stocks fluxes permanent forest plots distributed globally. This synthesis plot networks across climatic biogeographic gradients shows that dominated by high daytime temperatures. extreme condition depresses growth rates shortens time resides ecosystem killing under hot, dry conditions. The effect temperature worse...
Abstract Non-structural carbohydrates (NSC) are major substrates for plant metabolism and have been implicated in mediating drought-induced tree mortality. Despite their significance, NSC dynamics tropical forests remain little studied. We present leaf branch data 82 Amazon canopy species six sites spanning a broad precipitation gradient. During the wet season, total (NSC T ) concentrations both organs were remarkably similar across communities. However, its soluble sugar (SS) starch...
Abstract Tropical forests face increasing climate risk 1,2 , yet our ability to predict their response change is limited by poor understanding of resistance water stress. Although xylem embolism thresholds (for example, $$\varPsi $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>Ψ</mml:mi> </mml:math> 50 ) and hydraulic safety margins HSM are important predictors drought-induced mortality 3–5 little known about how these vary across Earth’s largest tropical forest. Here,...
Abstract The tropical forest carbon sink is known to be drought sensitive, but it unclear which forests are the most vulnerable extreme events. Forests with hotter and drier baseline conditions may protected by prior adaptation, or more because they operate closer physiological limits. Here we report that in South American climates experienced greatest impacts of 2015–2016 El Niño, indicating greater vulnerability temperatures drought. long-term, ground-measured tree-by-tree responses 123...
The carbon sink capacity of tropical forests is substantially affected by tree mortality. However, the main drivers death remain largely unknown. Here we present a pan-Amazonian assessment how and why trees die, analysing over 120,000 representing > 3800 species from 189 long-term RAINFOR forest plots. While mortality rates vary greatly Amazon-wide, on average are as likely to die standing they broken or uprooted-modes with different ecological consequences. Species-level growth rate single...
Abstract Peatlands are some of the world’s most carbon-dense ecosystems and release substantial quantities greenhouse gases when degraded. However, conserving peatlands in many tropical areas is challenging due to limited knowledge their distribution. To address this, we surveyed soils plant communities Colombia’s eastern lowlands, where few have previously been described. We documented peat >40 cm thick at 51 more than 100 wetlands. use our data update a regional peatland classification,...
Understanding the capacity of forests to adapt climate change is pivotal importance for conservation science, yet this still widely unknown. This knowledge gap particularly acute in high-biodiversity tropical forests. Here, we examined how Americas have shifted community trait composition recent decades as a response changes climate. Based on historical trait-climate relationships, found that, overall, studied functional traits show shifts less than 8% what would be expected given observed...
Abstract Aim Water availability is the major driver of tropical forest structure and dynamics. Most research has focused on impacts climatic water availability, whereas remarkably little known about influence table depth excess soil processes. Nevertheless, given that plants take up from soil, supply are likely to be modulated by conditions. Location Lowland Amazonian forests. Time period 1971–2019. Methods We used 344 long‐term inventory plots distributed across Amazonia analyse effects...
Abstract The forests of western Amazonia are among the most diverse tree communities on Earth, yet this exceptional diversity is distributed highly unevenly within and communities. In particular, a small number dominant species account for majority individuals, whereas large locally regionally extremely scarce. By definition, contribute little to local richness (alpha diversity), importance in structuring patterns spatial floristic turnover (beta diversity) has not been investigated. Here,...
Despite the progress in measurement and accessibility of plant trait information, acquiring sufficiently complete data from enough species to answer broad‐scale questions functional ecology biogeography remains challenging. A common way overcome this challenge is by imputation, or ‘gap‐filling' values. This has proven appropriate when focusing on overall patterns emerging database being imputed. However, some applications force imputation procedure out its original scope, using imputed...
Understanding how the traits of lineages are related to diversification is key for elucidating origin variation in species richness. Here, we test whether richness among trees from all major biogeographical settings lowland wet tropics. We explore mortality rate, breeding system and maximum diameter richness, either directly or via associations with range size, 463 genera that contain tropical forest trees. For Amazonian genera, also mean species-level size. Lineages higher rates—faster...
Abstract Rural communities in Amazonia rely on harvesting Mauritia flexuosa fruit, a dominant peatland palm, for their subsistence and income. However, these palms are felled to harvest the fruits, which has led reduced resource availability due pressure exerted by increasing fruit demand. As result, climbing been proposed as means fruits sustainably. long‐term ecological socio‐economic impacts of climbing, rather than felling, remain unknown. We evaluate whether M. populations production...
Remote sensing data could increase the value of tropical forest resources by helping to map economically important species. However, current tools lack precision over large areas, and remain inaccessible stakeholders. Here, we work with Protected Areas Authority Peru develop implement precise, landscape-scale, species-level methods assess distribution abundance arborescent Amazonian palms using field data, visible-spectrum drone imagery deep learning. We compare costs time needed inventory...
Abstract The peat‐forming wetland forests of Amazonia are characterized by high below‐carbon stocks and supply fruit, fibres timber to local communities. Predicting the future these ecosystem services requires understanding how hydrological conditions related tree species composition presence, or absence, peat. Here, we use continuous measurements water table depth over 2.5 years manual pore‐water pH electrical conductivity understand ecohydrological controls variables across large peatland...
Abstract Dipteryx timber has been heavily exploited in South America since 2000s due to the increasing international demand for hardwood. Developing tools genetic identification of species and their geographical origin can help promote legal trading timber. A collection 800 individual trees, belonging 6 different species, was genotyped based on 171 molecular markers. After exclusion markers out Hardy–Weinberg equilibrium or with no polymorphism low amplification, 83 nuclear, 29 chloroplast,...
Abstract Dominance of neotropical tree communities by a few species is widely documented, but dominant trees show variety distributional patterns still poorly understood. Here, we used 503 forest inventory plots (93,719 individuals ≥2.5 cm diameter, 2609 species) to explore the relationships between local abundance, regional frequency and spatial aggregation in four main habitat types western Amazonia. Although abundance‐occupancy relationship positive for full dataset, found that among...
Abstract Patterns of gall‐inducing insect diversity tend to be influenced by both habitat‐related and plant‐related characteristics. We investigated the distribution patterns galling insects in four vegetation types ( terra firme forest, white‐sand dry wet forest palm swamp forest) Peruvian Amazon test if gall (1) differs among different (2) depends on host plant richness. In total, we found 11,579 galls belonging 249 morphotypes, distributed across 30 botanical families 75 species. Among...
